I can only compare the NES ROMs to actual NES dumps, and just looking at Balloon Fight (compared to the Animal Crossing ROM, the one I happen to have available to compare), I see only one byte difference in the actual ROM, but Nintendo used a different header (and a footer), it seems.

Nintendo seemed to do a bunch of fiddling for the VC, I already dumped a bunch of these GBA roms but my hashes don't seem to compare properly to yours. When you extract the roms from RAM, they come bit-flipped and you have to fix them, keep that in mind. I got a little C program to do that, you might want to check your roms load in mGBA first and if not run them through: https://drive.google.com/open?id=0B09Zq ... 0JZbVdjYWM

If it's on my end, certainly egg on my face. I grabbed roms using inject_gba to extract them and then TCPGecko to extract from RAM and double-check. If you're interested in checking inject_GBA out, the original repo is here: https://github.com/ajd4096/inject_gba but it has a bum GUI implement that never got done and throws an error unless you fiddle with it a bit. I forked it and lopped off everything that seemed to point at that but I'm not sure if it's quite right (I know nothing about python yet, still) https://github.com/Hking0036/inject_gba-nogui Sorry that everything is a bit sparse.

The fact that only 5 ROMs are different / not existent and the rest being fine, I would say my method is not wrong. But I still wait for a reply telling me if any of this is of ANY use for no-intro. ^^
